For a limited time — reportedly through Sept. 30 — guests can receive a free Dave’s Single with any purchase by using the restaurant chain’s app. The deal is good once per day. The move follows McDonald’srecently adding long-term deep discounts to its app, including a daily $1 sandwich.

However, McDonald’s has since walked back that particular deal.

The price of the sandwich has doubled to $2 — still a bargain for most sandwiches — and is only available once a week through the end of September, instead of every day. The other long-term deals at McDonald’s still apply, including the $1 any size coffee deal, good daily through Dec. 30.

24/7 no more

If you want to sit down and eat during the wee hours in San Bernardino, your choices are once again limited to Denny’s and IHOP, now that Roger’s Burgershas cut its hours.

The restaurant, which opened in early July, is no longer open 24 hours a day during the week.

Roger’s, 591 N. D St., is now open 6 a.m.-2 a.m. Sunday through Thursday. It’s still open round-the-clock on Friday and Saturday. The chain has also announced a future location in Riverside, as well as ones in Whittier, Long Beach and San Diego.

Another try in Rialto

Here we go again. The building at 601 E. Foothill Blvd., Rialto, has a new occupant. Again.

The latest? King Gourmet, a Chinese restaurant.

The spot has been a revolving door of sorts, randomly switching back and forth between Mexican and Asian cuisines.

The space, which most recently was U8 Chinese and Thai Food, has been home to more than a half a dozen restaurants over the last five years or so, including Tasty Goody Chinese Fast Food, Aldo’s Mexican Food, Ajuberto’s, El Mitote Tacos & Beer, Culichi Taco and Panda Wok Chinese Food.
